[gdal-dev] GDAL 1.5, TileService and TileCache

[Guillaume Sueur]

I can't use TileCache because the client doesn't want to add mod_python
to his apache...
So, I'm looking for a way to generate tiles from a WMS server and use
them locally.

Thanks for your answer, and happy holidays for all of you !
